1 Configuration of System V init under Debian GNU/Linux
3 Most Unix versions have a file here that describes how the scripts
4 in this directory work, and how the links in the /etc/rc?.d/ directories
5 influence system startup/shutdown.
7 For Debian, this information is contained in the policy manual, chapter
8 "System run levels and init.d scripts". The Debian Policy Manual is
11 http://www.debian.org/doc/debian-policy/#contents
13 The Debian Policy Manual is also available in the Debian package
14 "debian-policy". When this package is installed, the policy manual can be
15 found in directory /usr/share/doc/debian-policy. If you have a browser
16 installed you can probably read it at
18 file://localhost/usr/share/doc/debian-policy/
20 Some more detailed information can also be found in the files in the
21 /usr/share/doc/sysv-rc directory.
23 Debian Policy dictates that /etc/init.d/*.sh scripts must work properly
24 when sourced. The following additional rules apply:
26 * /etc/init.d/*.sh scripts must not rely for their correct functioning
27 on their being sourced rather than executed. That is, they must work
28 properly when executed too. They must include "#!/bin/sh" at the top.
29 This is useful when running scripts in parallel.
31 * /etc/init.d/*.sh scripts must conform to the rules for sh scripts as
32 spelled out in the Debian policy section entitled "Scripts" (ยง10.4).
34 Use the update-rc.d command to create symbolic links in the /etc/rc?.d
35 as appropriate. See that man page for more details.
